We study the spatial and temporal variability of summer marine fog in the Chukchi–Beaufort region (175°E–150°W, 70°N–86°N) using the in-situ visibility measurements aboard the Chinese research fleet Xuelong (I and II) and a fog product we derive using the Vertical Feature Mask product of the spaceborne CALIPSO observations. The Xuelong in-situ observations show that the fog frequency in the Chukchi–Beaufort region has a maximum of ~18% in the early morning and is less than 10% in the rest of the day. The latitudinal distribution of the Xuelong-based in-situ fog frequency further shows high fog occurrences at 74°N and 79°N, which are related to the local high fog occurrences near 72°N–74°N and 76°N–80°N in the central Chukchi–Beaufort region, as revealed by the longitude-latitude pattern of the CALIPSO-based spaceborne fog frequency distribution. The CALIPSO-based fog frequency is also shown to be lower along the continental coastlines than in the Chukchi–Beaufort region. This longitude-latitude distribution ... : The data was originally obtained freely from https://www.chinare.org.cn/en/metadata/c381eed1-0fe0-4efd-a4ab-4f099cf2c6ad.
